How much power can the stock rods in a 383 B handle with a blower?

I could be wrong but I don't think 2.2 psi of boost and a 50-shot of nitrous will make 600hp on a stock-stroke 9:1 383 with a cam and ported stock heads. More like 500, if that. I feel like that low of boost pressure would barely even overcome parasitic losses of driving the blower itself. Stock rods might hold up. Now if we were talking 6 psi and a 150-shot, much less likely.
